动物的翅膀在飞行过程中会变形，以增强升力，便于飞行控制，并减轻伤害。监测机翼的结构和空气动力学状态具有挑战性，因为变形是被动的，并且流场是不稳定的;它需要分布式机械传感器来响应机翼上的局部气流和应变。如果没有传感器阵列的完整地图，就不可能对它们所支持的控制策略进行建模。在这里，我们提出了第一个系统的表征mechanosensors的翅膀：形态，分布和布线。通过将传感器分布的跨物种调查与定量神经解剖学和高保真度有限元分析相结合，我们表明，机械传感器能够很好地感知与飞行相关的机翼动力学特征。这项工作描述了翅膀感觉器官的整体和推进我们的理解的感觉运动回路，有利于精致的飞行控制动物具有高度可变形的翅膀。蜻蜓翅膀由大量的感觉神经元支配机械传感器以一致的模式分布在翅膀的整个跨度上翅膀感觉神经元的轴突被缩放以补偿传输延迟解剖学精确的模型揭示了告知传感器分布的翅膀应变场昆虫学;动物生理学;感觉神经科学;生物力学
Animal wings deform during flight in ways that can enhance lift, facilitate flight control, and mitigate damage. Monitoring the structural and aerodynamic state of the wing is challenging because deformations are passive, and the flow fields are unsteady; it requires distributed mechanosensors that respond to local airflow and strain on the wing. Without a complete map of the sensor arrays, it is impossible to model control strategies underpinned by them. Here, we present the first systematic characterization of mechanosensors on the dragonfly’s wings: morphology, distribution, and wiring. By combining a cross-species survey of sensor distribution with quantitative neuroanatomy and a high-fidelity finite element analysis, we show that the mechanosensors are well placed to perceive features of the wing dynamics relevant to flight. This work describes the wing sensory apparatus in its entirety and advances our understanding of the sensorimotor loop that facilitates exquisite flight control in animals with highly deformable wings. Dragonfly wings are innervated by an extensive collection of sensory neurons Mechanosensors are spread across the whole span of the wing with consistent patterns The axons of wing sensory neurons are scaled to compensate for transmission latencies Anatomically accurate models reveal wing strain fields that inform sensor distribution Entomology; Animal physiology; Sensory neuroscience; Biomechanics
